Controlled Steel wrench


 Drop forged in the USA... Controlled Steel was a brand name used by the JP Danielson Toolmaking concern. According to Alloy Artifacts (again) it would probably date to the 1930s, the small 6.5 A  marking refers to the nominal length of the tool- 6.5"- no explanation for the "A".
